Abstract

One of the leading factors of intensification of cultivation processes of agricultural products is crop rotation. Mineral fertilizers are also an essential element of farming systems. The aim of the work was to determine the influence of these two factors and their combinations on biological yield and structure of winter wheat harvest. The studies were carried out in 2019-2021 on stationary field experiment of the Federal State Budgetary Scientific Institution Federal Agricultural Kursk Research Center in Medvenskiy district of Kursk region. The soil is typical heavy loamy black soil. Winter wheat was cultivated in 3 crop rotations, where the forecrops were black fallow, green manure fallow (peas) and sown fallow (horse beans). The scheme of the experiment included for 4 levels of fertilization: without fertilizers, N60P60K60, N80P80K80, N100P100K100 kg a.i. per 1 ha. Black fallow showed the highest biological yield on high background of fertilization, as for medium and low fertilization, and also without fertilizers - on green manure. Increase of doses of mineral fertilizers provided a yieldincrease. Total and productive bushiness of winter wheat was higher in combination with green manure fallow, and the weight of 1000 grains and the number of grains in the wheat head of the main stem were higher in case of black fallow. The harvest structure parameters were lower in crop rotationthan in the other two rotations. A tendency ofparameter increase of the harvest structure was revealed: total and productive bushiness, weight of 1000 grains, the number of grains in the wheat head of the main stem in case of fertilizationlevelincrease. A close positive relationship was established between the biological yield of the crop and the total (r = 0.958) and productive (r = 0.956) bushiness, as well as the number of grains in the wheat head of the main stem (r = 0.911).

中部黑土区条件下生产集约化对冬小麦生物产量及收获结构的影响

农产品种植过程集约化的主要因素之一是作物轮作。矿物肥料也是农业系统的重要组成部分。研究这两个因素及其组合对冬小麦生物产量和收获结构的影响。该研究于2019-2021年在库尔斯克州梅德文斯基区的联邦国家预算科学机构联邦农业库尔斯克研究中心的固定田间试验中进行。土壤为典型的重质壤土。冬小麦分为3个轮作，其中前茬为黑色休耕、绿肥休耕(豌豆)和播种休耕(马豆)。试验方案包括4个施肥水平:不施肥、N60P60K60、N80P80K80、N100P100K100 kg a.i.每公顷。黑色休耕在高施肥背景下的生物产量最高，中、低施肥背景下的生物产量最高，绿肥背景下的生物产量也最高。增加矿质肥料的用量增加了产量。绿肥休耕的冬小麦总产量比绿肥休耕高，黑色休耕的千粒重和主茎穗粒数比绿肥休耕高。作物轮作的收获结构参数低于其他两种轮作。结果表明，在施肥水平增加的情况下，收获结构参数增加的趋势是:总产重、千粒重、主茎穗粒数增加。作物的生物产量与总产量(r = 0.958)、生产产量(r = 0.956)、主茎穗粒数(r = 0.911)呈极显著正相关。
